I am not sure the above configuration switches are valid in FreeBSD5.3
system.  I could not find the relevant code in my /etc directory...

Basically, when net.inet6.ip6.forwarding is set to 1, the node will
not accept RA messages.  However, in our current MR implementation, we
always accept RA messages regardless the value of the switch.

Do you have any problem if your mobile router gets autoconfigured
addresses on the ingress interface?
